Question

in the figure., AB||CD||EF. Find the value of x​

Answer 1

$\angle{FEC} + \angle{ECD}$ = 180°....(co-interior angle)

=> $130° {+} \angle{ECD}$=180°

=> $\angle{ECD}$=180°–130°

=> $\angle{ECD}$=50°

$\angle{ABC}{=} \angle{BCD}$ = 80°....(interior alternate angle)

=> $\angle{BCD}$ = 80°

=> $\angle{FCD} + \angle{BCE}$ = 80°

=> $50° + x°$= 80°

=> $x°$= 80°–50°

=> $x°$= 30°
